I definitely have the Cp patch installed, which I believe is the one needed to allow MyStuff to detect the long keypresses.

The only other factor I can think of is that I was only trying this with files I'd edited using CutAds, for which MyStuff was reporting the wrong duration (i.e. the duration before the ads were cut out)

Thanks for the quick replies and feedback -- it's useful to know that it ought to work, and it's apparently just me that's the problem. That means there's a chance I'll be able to fix it somehow.

I suspect that you copied the MyStuff tap to your toppy rather than used the MyStuff installer (possibly because you can't run windows programs). I base this on the fact that your signature shows several missing patches (AbFmMhRaSlSyVrXl) and that other support taps are not present.

For proper use of MyStuff, you need to apply most of the missing patches

That may depend on your setting for S1: Exclusive Mode, but actually ISTR that MyStuff won't update the durations until you restart it. The same may (in this case) be true for the played flag, particularly as MyStuff will already be confused about where x% through the file actually is anyway.

Yes, you're right; I have S1 set to Extreme, but even after pressing 0 to force a reload, MyStuff still shows the original pre-editing duration (though it does seem to update the file size information). The only way I could get the duration to update consistently was to exit MyStuff and then start it up again, but I've found that works well enough if I save up a bunch of edits and then run CutAds to apply them all at once.
